Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

hat the 3 pathways act in concert probably enables the organism to find phosphates in different chemical states or environmental conditions, or even to exploit the phosphates found in other M. xanthus cells or those of potential prey organisms. Dr Whitworth found that:

The potential complexity of the information on phosphate levels the bacterium can process is significantly increased by the findings that there are three phosphate signalling pathways, with considerable interaction between the three pathways.

A further additional partial pathway also acts as a phosphate level detector - giving the bacterium even more tools to employ as a phosphate gourmet.

Dr Whitworth also has evidence that the surprising extent of interaction between the three and a half phosphate signalling pathways is also found among the other 140 plus signalling pathways of the bacterium. If three and half pathways are enough to make it a phosphate gourmet, the level of interactions between up to 150 pathways will easily be enough to give Myxococcus xanthus its precocious social skills.
